The purpose of this paper is to examine whether Western human resource (HR) theory is applicable to a call centre located in the Philippines. A call centre, due to the amount of emotional labour involved in this type of work, is an ideal environment to study stress related Western HR model where stress eventually leads to turnover. Turnover is a major concern in the call centre industry.

The authors tested a model linking work stress to job satisfaction, organizational commitment and intention to turnover using data collected from 439 employees in the Philippines. Both correlation analysis and partial least squares analysis were used to test the theoretical Western HR components both individually and holistically.

The findings indicate that these call centre employees reported emotional stress, leading to job dissatisfaction, reduced organization commitment and ultimately increased intention to turnover. Turnover is reported to be a serious and increasing problem in call centres and this research demonstrates the significant role of employee emotional stress.

An understanding of the applicability of Western HR theory in non-western countries is of interest to managers in non-western countries. It is important as economic development occurs in newly developing countries that managers understand which theories from developed nations will apply to facilitate their growth and success.

This paper addresses HR concerns both in a Pan-Asian country that is rapidly developing and in the call centre industry which is predicted to grow rapidly in future.

IN 1887 A. M. Wellington discussed in his book Economic Theory of the Location of Railways the way in which railroad layout could affect the development of the surrounding regions. At one point he analysed the cost/value relationship of two possible sites for a railway bridge near the fork of a river and decided that the more difficult site, despite higher costs, was preferable because it would provide a better basis for industrial growth and commerce in a city there.

L'activité économique des stations thermales a pris aujourd'hui un tournant important. Après des décennies de conflit entre le thermalisme et la médecine clinique et pharmacologique, les stations thermales ont reçus aujourd'hui une nouvelle mission toute aussi précise qu'importante pour l'humanité.

Patients with chronic obstructive pulmonary disease (COPD) suffer from many health problems including poor sleep. This paper aims to evaluate the relationship between diet quality indices (DQIs) and sleep quality in COPD.

The current cross-sectional study was carried on 121 COPD patients. Subjective quality of sleep was determined by Pittsburgh Sleep Quality Index (PSQI) and categorized into “poor” and “good” sleep quality. Dietary history was assessed by the DQIs. Disease status was categorized according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) Guidelines.

In total, 103 men and 18 women with a mean age of 66.1 ±10.9 were studied. The subjects were categorized into four groups based on GOLD; 3.3% of subjects were at Stage 1, 38% in Stage 2, 38% in Stage 3 and 20.7% in Stage 4. In total, 38% of subjects were good, and 62% were bad sleepers according to PSQI score. There was no significant relationship between the severity of COPD and PSQI score. We observed a significant inverse relation between PSQI total score and Mediterranean diet (MED) scale, Healthy Eating Index (HEI)-2010 and HEI-2005 (p = 0.024, 0.037 and 0.024, respectively) in males.

This study showed a high prevalence of poor quality of sleep and sleep disturbances among COPD patients. There was an inverse association between PSQI and sleep disorders and DQIs scores in COPD patients. Regardless of the severity of airflow obstruction, poor diet quality may constitute a risk factor for sleep quality.

This paper aims to develop a method to measure the length of cracks inside solder joints, which enables the validation of computed tomography (CT) crack length measurements.

Cracks were formed inside solder joints intentionally by aging solder joints of 0603 size resistors with thermal shock (TS) test (−40 to +140°C, 2,000 cycles), and CT images were captured about them with different rotational increment (1/4, 1/2 and 1°) of sample projection. The length of cracks was also measured with our method, which is based on capturing high-resolution radiography X-ray images about the cracks in two perpendicular projection planes. The radiography results were compared to the CT measurements. The percentage error for the different CT rotational increment settings was calculated, and the optimal CT settings have been determined.

The results have proven that reducing the rotational increment increases the sharpness of the captured images and the accuracy of crack length measurements. Nevertheless, the accuracy compared to high-resolution radiography measurements is only slightly better at 1/4° rotational increment than in the case of 1/2° rotational increment. It should be also noted that the 1/4° increment requires twice as much time for capturing the images as the 1/2° increment. So, the 1/2° rotational increment of sample projection is the optimal setting in our investigated case for measuring crack lengths.

The developed method is applicable to find the optimal settings for CT crack length measurements, which provides faster analysation of large quantity samples used, e.g. at life-time tests.

There is a lack of information in the literature regarding the optimisation of CT measurement set-up, e.g. a slightly larger value of the sample rotational increment can provide acceptable resolution with much faster processing time. Thus, the authors developed a method and performed research about optimising CT measurement parameters.

Presents a simple methodology for managing service quality that takes into joint consideration of what customers expect to receive and what the service provider can offer. A four‐step procedure explains the derivation of the customer‐service provider matrix (CSM). Customer feedback and data on an international coffee outlet are employed to demonstrate the application of the CSM as a visual tool. Two versions of the CSM matrix are developed; one with raw data and another with an illustrative weighting procedure. Service providers can prioritize and re‐allocate resources to increase the levels of the attributes of services quality that would be valued by customers.

This paper aims to develop an adaptive unscented Kalman filter (AUKF) formulation for orientation estimation of aircraft and UAV utilizing low‐cost attitude and heading reference systems (AHRS).

A recursive least‐square algorithm with exponential age weighting in time is utilized for estimation of the unknown inputs. The proposed AUKF tunes its measurement covariance to yield optimal performance. Owing to nonlinear nature of the dynamic model as well as the measurement equations, an unscented Kalman filter (UKF) is chosen against the extended Kalman filter, due to its better performance characteristics. The unscented transformation of the UKF is shown to equivalently capture the effect of nonlinearities up to second order without the need for explicit calculations of the Jacobians.

In most conventional AHRS filters, severe problems can occur once the system suddenly experiences additional acceleration, resulting in erroneous orientation angles. On the contrary in the high dynamic accelerative mode of the new proposed filter the errors would not suddenly increase, since the additional to cruise accelerations are being continuously estimated resulting in substantially more accurate orientation estimation. This feature causes the associated filter errors to gradually increase, in the event of continuous vehicle acceleration, up to a point of zero additional acceleration that subsequently causes a subsidence of the error back to zero.

The proposed filtering methodology can be implemented for orientation estimation of aircraft and UAV that are equipped with low‐cost AHRSs.

Traditional AHRS algorithms utilize the accelerometers output for the computation of roll and pitch angles and magnetometer output for the heading angle. Moreover, these angles are also calculated from the gyroscopes output as well, but with errors that increase with time. Of course for some applications of AHRS system, orientation errors can be damped out with a proportional‐integral controller. In such a case, the filter cut‐off frequency is usually selected experimentally. But, for high accelerating vehicles utilizing AHRS, the system errors can become very large. A possible remedy to this problem could be to use more advanced nonlinear filter algorithms such as the one proposed.

On April 4, 2007, Don Imus, one of the company&s most popular talk show personalities made comments on the air regarding the Rutgers women&s basketball team. According to the transcription from Media Matters for America, Imus said, “ That&s some nappy-headed hos there. I&m gonna tell you that now, man, that&s some … woo. And the girls from Tennessee, they all look cute, you know, so, like … kinda like … I don&t know.” At first, the comments did not seem out of the ordinary for one of radio&s “shock jocks.” However, as the public reaction grew, the situation changed considerably. Under pressure from the public, Moonves reluctantly suspended Imus. But it was too little too late. By the end of the day on April 11, analysts estimated that $2.5 million in advertising revenue was lost. On April 12, Moonves terminated Don Imus& contract.

After Moonves fired Imus, there was still a lot to consider. He really wanted a way for the company to meet the demands of the company&s stakeholders. In addition, he wanted to avoid any more distractions from the firm&s normal day-to-day operations.
